Brilliant!
Haven't gotten arond to addressing the peaking coild yet. Hopefully this evening.
Neverthe less have been letting the chassis run. I reformed the electrolytics before powering and they seem fine. All the voltages seem correct so far up to the sync separator. I can see composite video on the scope and horizontal sync good. V ertical a bit touchy. Remember I recreated the couplate PC-101 integrator network. Seems the problem goes back to the vertical sync separator where the voltages are a bit low and the sync output appears a bit low.
The HV is holding at 21 kV. The vertical convergengence transformer seems fine so far.
A longer run for over an hour produced the new resistive ballast unit temperature reaching 75 degrees celcius. Too hot to leave your finger on but a lot less than the 125 degrees I measured when it was clamped to the chassis.
